Storage system and application intercommunication is provided. A first kernel-mode module determines a first event corresponding to an operational parameter of a first node based, at least in part, on a shared namespace accessible by the first kernel-mode module and a second kernel-mode module. An interrupt is issued based on the first event from the first kernel-mode module to the second kernel-mode module via an interface. The second kernel-mode module issues a second event to a second node, wherein the second event corresponds to the object of the shared namespace.
